Another sidenote is that I'd rather invest more money into the successor of the D300s when it eventually comes out. So in the mean time, I'll be picking up the D90 and feel confident about my final decision.
For me personally, it's outweighing the pros / cons and subtle differences for the warranted price increase. At this point the D300s doesn't have enough major differences that I can justify dropping an extra $700.00.
I have been published a few times had some corporate gigs while shooting with my D80. As others have said, it's not the tools that makes you a great photographer... It's your use of said tools.
I appreciate everyone's input and just for the record I do consider myself on a higher level than the "average photographer". The average photographer doesn't take his/her gear everywhere they go, constantly looking for new lines and ideas for a shoot. Even while driving I scout vantage points and framing for new photoshoots.
It's our passion for photography that sets us apart from some guy with a boatload of "better gear" who doesn't know how to use it.
Have a great week everyone.
